When did God deal only with the Jewish people?
God dealt only with the Jewish people from Genesis chapter 12 until the Book of Acts, with only very few exceptions. This period covered the Abrahamic Covenant, the giving of the Law, and the Temple, focusing on the nation of Israel.
Les explains that from Genesis chapter 12 until the Book of Acts, God dealt with Jew only, with some exceptions, but very, very few. Everything from Genesis chapter 12 and the Abrahamic Covenant dealt with the nation of Israel, giving them the Law and the Temple. The plan was that one day God would funnel them back into the ungodly river of humanity and bring them a knowledge of the God of Abraham, Isaac, and Jacob. That was God's noble plan in His sovereignty, but it did not work because Israel did not believe it.
